I'm curious to know if any other PrimeTest 300 or 350 users have ever experienced this? It has only happened a few times but has occured on our oldest 300's and our newest 350's. Basically the units reset themselves (!?) back to factory settings. So all the user accounts disappear leaving only an open (no password) Admin account and a User 1 and User 2 account. We are using Rev 3.61. I've never noticed it with any earlier revisions, although it has only occured a few times across a dozen or so units so impossible to relate to anything.

Thanks for that - seems you're right. I have now had it happen. The batteries gave out mid test, the unit shut off. When restarted with fresh batteries all the user accounts and passwords had gone. So if you need to keep these settings and the admin account secure make sure you replace the batteries in good time!

I'm sorry to hear that you have lost faith in Seaward - I hope that we can do something to restore your faith. I've spoken with our engineering department and tried to reproduce this problem myself. I added a number of new test sequences on my PT350 and also setup a number of user accounts. I tried removing power (by popping out a battery) both when the unit was idle and also mid test. When I replaced the batteries the new sequences and new users accounts were as I had configured them. I'll try this again but allowing the batteries to discharge.

Does this happen under any particular set of circumstances or during any particular test? If we can reproduce it then it can be fixed.

I have had it happen again this week. With one bar showing on the battery health indicator (not flashing), and visual inspection data input, the 350 shutdown at the point of starting a 500V insulation test.Changed batteries and switched on to find the only user names available were admin, user 1 & user 2, the test & tag logo, test options and preferences all needed to be reset. All my user tests were ok.

One of the team has just had it happen 3 times in as many days on an old PT300. User defined Logo gone All user accounts gone, new open admin, user1 and user2, accounts created, etc.

I've just seen a new spurious fault on one of the older PT350's too. The display took about 30 seconds to respond to a key press. I think sometimes it responded with an incorrect character - difficult to tell though due to the long delay. It got very confusing. Powering down for a while cleared it.
